CRC Service Description
CRC Service Description
This “service” differs from the preceding ones in that it is structured differently: it is composed of
an array and some methods directly accessible via the
Description
This function provides a table driven 32bit CRC generation for
byte data. This CRC is known as the CCITT CRC32.
Input Parameters:
Pointer on the data buffer.
The size of this buffer.
A pointer on the result of the CRC.
Output Parameters:
None.
This function provides a table driven 16bit CRC generation for
byte data. This CRC is calculated with the POLYNOME 0x8005
Input Parameters:
Pointer on the data buffer.
The size of this buffer.
A pointer on the result of the CRC.
Output Parameters:
None.
This function provides a table driven 16bit CRC generation for
byte data. This CRC is known as the HDLC CRC.
Input Parameters:
Pointer on the data buffer.
The size of this buffer.
A pointer on the result of the CRC.
Output Parameters:
None.
This function provides a table driven 16bit CRC generation for
